Saelig Debuts New Low-cost Wireless RaspberryPi Modules

Pittsford, NY, USA:  Saelig Company, Inc. has introduced the eRA-Connect2-Pi – a USB module that provides a simple wireless bridge between two Raspberry Pi’s (Pi2Pi), or a Raspberry Pi and a PC or any other device that supports USB serial communications.  Utilizing seamless easyRadio technology at 915MHz (ISM) bands, the eRA-Connect2-Pi provides considerably greater range and less power consumption than similar WiFi or Bluetooth modules operating in the overcrowded 2.4GHz bands. Frequency, bandwidth, power output and data rate can optionally be configured to allow multiple devices to communicate free from interference from each other and any other RF devices. 

eRA-Connect2-Pi incorporates an eRA900TRS wireless module which provides simple-to-use, out-of-the-box wireless serial communication as a COMport.  eRA-Connect2-Pi features include allowing users to change the radio bandwidth from 150kHz down to a remarkable 12.5kHz, providing narrow-band performance at a wide-band budget. Internal temperature compensation insures less than 1.5kHz frequency drift from ambient 20degC over a range of -40degC to +85degC. This new feature may also be output as a temperature measurement for the end user equipment, accurate to within 1degC.

No complex RF protocol software is required to create an instant bidirectional link. The low-consumption eRA-Connect2-Pi can be powered directly from Raspberry Pi’s USB port. An integral SMA antenna connector allows for use of an off-board antenna.  Transmit and Receive LEDs are provided to confirm communication operation.

Host devices can send and receive half duplex communications of up to 180 bytes of data per packet, seamlessly delivered to other hosts within range. There is no need for complicated ‘bit balancing’ or elaborate coding schemes.

Other innovative features available on eRA modules include:

Both Linux and Windows drivers are provided. 

Made by European short-range radio specialists Low Power Radio Solutions (LPRS), the eRA-Connect2-Pi is available now from stock from Saelig Company Inc. Pittsford, NY.
